PRIORITY CLAIM AND RELATED APPLICATIONS

This application is a continuation of International Patent Application No. PCT/CN2015/070328, filed on Jan. 8, 2015. This application claims the benefit and priority of Chinese Patent Application No. 201410035894.8, filed on Jan. 24, 2014. The entire disclosure of each of the above applications is incorporated herein by reference.

FIELD OF THE INVENTION

The disclosed embodiments relate to the field of computers, and in particular, to methods and systems for verifying an account operation.

BACKGROUND OF THE INVENTION

When using the Internet, a user may ensure the security of a user account by setting account verification information or using an account verification tool, so that situations such as malicious or accidental account operations, such as an accidental deletion of the user account can be prevented. For example, verification is performed by inputting a preset account password, and inputting a verification code received by a mobile phone bound to the user account beforehand, using a third-party verification platform such as an OpenID, and/or OAuth (open identification system). Verification may also be performed using a hardware device such as a password card, a USB key (mobile digital certificate), or an RSA (asymmetric cryptographic algorithm) certificate. However, when an internet user account is directly logged in on a mobile device, user account verification cannot be performed without setting account verification information, and the cost of using an account verification tool is high. In general, even when the account verification information is set, or an account verification tool is used, the account verification still suffers from low security, low reliability, and insufficiency in preventing a malicious deletion behavior of an account hacker.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the subject matter presented herein. But it will be apparent to one skilled in the art that the subject matter may be practiced without these specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.

The technical solutions of the present application are clearly and completely described below with reference to the accompanying drawings. It is obvious that embodiments to be described are only a part rather than all of the embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

In some embodiments of the present application, a computer system for account verification includes a server, and a user may log in to an account on a mobile device, such as a tablet computer, a smart phone, or may log in to an account through a client module on a mobile device, where the client module in the mobile device is, for example, a webpage browser client, an instant messaging client (such as QQ, WeChat, Weibo), and/or the like. A method, a system, and a device for account verification provided in the embodiments of the present application are applicable to various systems, such as an e-commerce system and/or an instant messaging application, which requires account verification. For example, account verification is performed on an account in an e-commerce system, for a login to an account in an instant messaging application system, or during one or more account operations, such as an account deletion.

As shown in FIG. 1, the account verification is implemented in a server-client environment 100 in accordance with some embodiments. In some embodiments, server-client environment 100 includes client-side processing 102-1, 102-2 . . . (hereinafter “client-side module 102”) executed on a client device 104-1, 104-2 . . . , and server-side processing 106 (hereinafter “server-side module 106”) executed on a server system 108. Client-side module 102 communicates with server-side module 106 through one or more networks 110. Client-side module 102 provides client-side functionalities (e.g., instant messaging, and social networking services) and communications with server-side module 106. Server-side module 106 provides server-side functionalities (e.g., instant messaging, and social networking services) for any number of client modules 102 each residing on a respective client device 104.

In some embodiments, server-side module 106 includes one or more processors 112, one or more databases 114, an I/O interface to one or more clients 118, and an I/O interface to one or more external services 120. I/O interface to one or more clients 118 facilitates the processing of input and output associated with the client devices for server-side module 106. One or more processors 112 obtain requests for performing account operations from one or more client devices 104, process the requests, identify usage data associated with the user account on the one or more client devices, verify the account information on the one or more client devices, and send the account verification results in response to the requests to client-side modules 102 of one or more client devices 104. The database 114 stores various information, including but not limited to, account information associated with each user, device information associated with each user account, and usage data associated with each user account on a certain client device. The database 114 may also store a plurality of record entries relevant to the activities of respective accounts of each user, and devices associated with each user. I/O interface to one or more external services 120 facilitates communications with one or more external services 122 (e.g., merchant websites, credit card companies, social network platforms, and/or other processing services).

Examples of client device 104 include, but are not limited to, a handheld computer, a wearable computing device, a personal digital assistant (PDA), a tablet computer, a laptop computer, a desktop computer, a cellular telephone, a smart phone, an enhanced general packet radio service (EGPRS) mobile phone, a media player, a navigation device, a game console, a television, a remote control, or a combination of any two or more of these data processing devices or other data processing devices.

Examples of one or more networks 110 include local area networks (LAN) and wide area networks (WAN) such as the Internet. One or more networks 110 are, optionally, implemented using any known network protocol, including various wired or wireless protocols, such as Ethernet, Universal Serial Bus (USB), FIREWIRE, Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Wi-Fi, voice over Internet Protocol (VoIP), Wi-MAX, or any other suitable communication protocol.

Server system 108 is implemented on one or more standalone data processing apparatuses or a distributed network of computers. In some embodiments, server system 108 also employs various virtual devices and/or services of third party service providers (e.g., third-party cloud service providers) to provide the underlying computing resources and/or infrastructure resources of server system 108.

Server-client environment 100 shown in FIG. 1 includes both a client-side portion (e.g., client-side module 102) and a server-side portion (e.g., server-side module 106). In some embodiments, data processing is implemented as a standalone application installed on client device 104. In addition, the division of functionalities between the client and server portions of client environment data processing can vary in different embodiments. For example, in some embodiments, client-side module 102 is a thin-client that provides only user-facing input and output processing functions, and delegates all other data processing functionalities to a backend server (e.g., server system 108).

In some embodiments, at least some of the functions of server system 108 are performed by client device 104, and the corresponding sub-modules of these functions may be located within client device 104 rather than server system 108. In some embodiments, at least some of the functions of client device 104 are performed by server system 108, and the corresponding sub-modules of these functions may be located within server system 108 rather than client device 104. Client device 104 and server system 108 shown in FIGS. 2A-2B, respectively, are merely illustrative, and different configurations of the modules for implementing the functions described herein are possible in various embodiments.

FIG. 3A is a flow chart of a method 300 for verifying an account operation in accordance with some embodiments. In some embodiments, method 300 is executed by a computer system (e.g., server system 108, FIGS. 1 and 2A) for verifying the account operation. Server system 108 receives (302) an account verification request which is sent by a mobile device (e.g., client device 104-1, FIGS. 1 and 2B) during a login to an account on mobile device 104-1. The account verification request includes a mobile device identifier (e.g., device ID).

Server system 108 obtains (304) historical usage of the account on mobile device 104-1 associated with the mobile device identifier. The historical usage data includes historical login data and/or historical operating data of the login to the account on mobile device 104-1 corresponding to the mobile device identifier.

Server system 108 determines (306), according to the historical usage data of the account on mobile device 104-1, whether the mobile device 104-1 associated with the mobile device identifier is a trusted device (i.e., a safe device). According to a determination result, server system 108 returns an account verification result to mobile device 104-1 in response to the account verification request.

In some embodiments, prior to receiving (302) the account verification request, server system 108 further generates two-dimensional code information and sends the two-dimensional code information to a target page, so that the target page generates a two-dimensional code according to the two-dimensional code information and displays the two-dimensional code on the target page.

In some embodiments, server system 108 generates two-dimensional code information, where the two-dimensional code information is information used for verifying account operation, such as an account login process, and server system 108 may dynamically generate two-dimensional code information according to different accounts. The two-dimensional code information may be a character string such as a token of WeChat, and server system 108 delivers the generated two-dimensional code information to a target page, where the target page may be a display page on a terminal device (e.g., client device 104-2, FIG. 1) such as a personal computer or a notebook computer. In some embodiments, terminal device 104-2 has been verified as being safe for a user account operation. In some embodiments, the target page may be a webpage or a page stored in terminal device 104-2. In some embodiments, the target page receives the two-dimensional code information, then generates a two-dimensional code according to the two-dimensional code information, and displays the two-dimensional code on the target page. Mobile device 104-1 is then required to scan the two-dimensional code in the target page by using a camera of mobile device 104-1, and parse the scanned two-dimensional code to obtain the two-dimensional code information to verify a login to an account on mobile device 104-1. In some embodiments, the two-dimensional code is, for example, a Quick Response (QR, a type of a two-dimensional code), and the like.

In some embodiments, prior to receiving (302) the account verification request, server system 108 further (1) obtains login operating data during a login to an account on mobile device 104-1; (2) determines whether the acquired login operating data of the account matches predetermined unsafe criteria, e.g., predetermined unsafe operating data; and (3) if the obtained login operating data of the account matches the predetermined unsafe criteria, sends an account verification instruction to mobile device 104-1. The account verification instruction may request for the device identifier associated with mobile device 104-1. In such implementations, mobile device 104-1 sends an account verification request including a device identifier according to the account verification instruction.

In some embodiments, system server 108 may acquire login operating data during a login to an account on mobile device 104-1. The login operating data includes login data during the login to the account and usage data after the login to the account. The login data, for example, account login data, during the login to the account, may further include a login address, a login platform, a login manner, and the like. The usage data includes, for example, a deletion operation of the account, a query for personal data, such as a personal identity, a mobile phone number, a friend of the account, a query for property information of the account, a change to the property information of the account, and the like.

Server system 108 determines whether the obtained login operating data of the account matches the predetermined unsafe criteria, e.g., predetermined unsafe operating data. In accordance with a determination that the obtained login operating data matches the predetermined unsafe criteria, server system 108 sends an account verification instruction to mobile device 104-1, so that mobile device 104-1 can send, according to the account verification instruction, to server system 108, an account verification request including the device identifier associated with mobile device 104-1. In some embodiments, the predetermined unsafe criteria include, but is not limited to: deleting the account, changing the property information of the account, one-time operating data such as property-related fraud information to be sent to a friend during instant messaging.

In some embodiments, the obtained login operating data of the account may be parsed and tokenized to obtain multiple keywords, and then the multiple keywords are compared with keywords in the predetermined unsafe operation data. If a keyword in the login operating data matches a keyword in the unsafe operating data, it is determined that the obtained login operating data of the account matches the predetermined unsafe criteria, and an account verification instruction is sent to mobile device 104-1, so that mobile device 104-1 can send, according to the account verification instruction to server system 108, the account verification request including the mobile terminal identifier. Therefore, detection and determination of an unsafe account operation can be implemented, and if it is determined that an unsafe account operation occurs, method 300 of FIG. 3A is executed, and account verification needs to be performed on the account to ensure security and reliability of the account operation.

In some embodiments, the account verification request sent from mobile device 104-1 during a login to an account and received (302) by server system 108 includes a device identifier. In some embodiments, the account verification request includes, but is not limited to, two-dimensional code information obtained by mobile device 104-1 scanning a two-dimensional code displayed on a target page and parsing the scanned two-dimensional code. The account verification request may further include other verification information, such as a password and a one-time pass code, inputted for the account. Server system 108 receives the account verification request which is sent by mobile device 104-1 and includes the mobile device identifier, where the mobile device identifier is a unique identifier of mobile device 104-1. In some embodiments, the mobile device identifier may be a unique hardware identifier of the mobile device, such as an embedded multimedia card identity (EMMC ID, which is a globally unique hardware identity of EMMC Flash, and is a 32-bit hexadecimal numerical value), a mobile equipment identifier identity (ME ID, which is a globally unique 56-bit mobile terminal identifier identity), and an International Mobile Equipment Identity (IMEI). The mobile terminal identifier may also be an identifier generated in a combination manner according to the hardware identifier of the mobile terminal.

In some embodiments, the historical data of an account corresponding to the mobile device identifier is obtained, where the historical data includes historical login data and/or historical operating data of the login to the account on mobile device 104-1 corresponding to the mobile device identifier. In some embodiments, the historical login data is the data obtained during a login to the account on mobile device 104-1. In some embodiments, the account login data includes, but is not limited to, a login frequency within a preset period, and the account login data may further include: a login Internet Protocol (IP), a login platform, or a login manner. The login platform is, for example, a mobile phone login client or a webpage login client. The login manner information is, for example, an automatic login, a login after input of a login protection answer, or a login after input of an account password.

The login frequency within a preset period may be the total number of logins within the preset period, and the preset period is a preset and editable period of time, such as 18 hours, 3 days, 15 days, and 30 days. The login frequency within a preset period is that, for example, there are 6 logins to WeChat on mobile device 104-1 within the last 15 days. In some embodiments, the preset period may further include multiple preset sub-periods, so the login frequency within a preset period includes that: the number of logins in each preset sub-period is greater than 1. For example, the preset period is 3 days, and each preset sub-period is 1 day, so the number of logins to WeChat on mobile device 104-1 each day is greater than 1.

The historical operating data includes, but is not limited to, a usage duration. The historical operating data further includes all operating records from a login to the account. Specifically, the use duration is a time interval from a login to the account and a latest operating record after the login to the account. For example, there are 2 logins to the account within one day. The first login takes place at 11:25, and the operating records are kept at 11:23, 12:00, . . . , 12:15, and 13:25. The second login takes place at 14:00. Therefore, within the time before the second login, the time, when an operating record is kept, closest to the second login is determined as the latest operating time in the first login, that is, 13:25 is determined as the latest operating time and it is calculated that the use duration is 2 hours.

In some embodiments, the historical data may further include a preset trusted identifier or a preset key. The preset trusted identifier is a mobile device identifier stored at server system 108 beforehand, and is a mobile device identifier which has passed security verification (i.e., qualified as being safe). The preset key is a key dynamically generated by server system 108 according to a preset algorithm, and the dynamically generated key is included in data exchanged on mobile device 104-1 each time, where mobile device 104-1 cannot decrypt the key. Server system 108 implements both the generation and parsing of the key, and the preset key delivered by server system 108 is included in the data returned by mobile device 104-1 to server system 108, so that server system 108 can perform decryption and verification on the preset key.

In some embodiments, server system 108 determines (306), according to the historical data of the account corresponding to the mobile device identifier, whether the mobile device identifier is a trusted identifier, and according to a determination result, an account verification response corresponding to the account verification request is returned to mobile device 104-1.

In some embodiments, if the historical login data includes a login frequency within a preset period, and the historical operating data includes a use duration, the determining whether the mobile device identifier is a trusted identifier according to the historical data of the account corresponding to the mobile device identifier may specifically include: if the login frequency within the preset period meets a preset frequency threshold, and/or the use duration meets a preset time threshold, server system 108 determines that the mobile device identifier is a trusted identifier.

For example, if an account 1 is logged in to on a mobile device 1, a preset period is 15 days, there are in total 8 logins to the account 1 by a client in mobile device 1 within 15 days, and a preset frequency threshold is at least 5 logins within 15 days, it can be determined that a mobile device identifier of mobile device 1 is a trusted identifier. If an account 2 is logged in to on a mobile device 2, a preset period is 3 days, there are 2 logins each day to the account 2 by a client in mobile device 2 within three days, a login frequency within the preset period is at least 2 logins each day, and a preset frequency threshold is that the number of logins in each preset sub-period is greater than 1, it can be determined that a mobile device identifier of mobile device 2 is a trusted identifier. If an account 3 is logged in to by a client on a mobile device 3, a use duration is 3 hours, and a preset time threshold is more than 2 hours, it can be determined that a mobile device identifier of mobile device 3 is a trusted identifier.

In some embodiments, if the login frequency within a preset period does not meet the preset frequency threshold, and/or the use duration does not meet the preset time threshold, it is determined that the mobile device identifier is an untrusted identifier.

In some embodiments, whether the historical data includes: a preset trusted identifier, the determining whether the mobile device identifier is a trusted identifier according to the historical data of the account corresponding to the mobile device identifier may specifically include determining whether the mobile device identifier is identical with the preset trusted identifier, if yes, the mobile device identifier is determined to be a trusted identifier.

The trusted identifier is a mobile device identifier added in server system 108 beforehand, and is a mobile device identifier which has passed security verification. If a preset trusted identifier that is identical on the mobile device identifier is found in the stored preset trusted identifiers, it is determined that the mobile device identifier is a trusted identifier.

In some embodiments, if the mobile device identifier is not identical with the preset trusted identifier, it can be verified in other manners whether the mobile device identifier is a trusted identifier.

In some embodiments, if the historical data includes: a preset key. After receiving (302) the account verification request, method 300 may further include parsing an account verification request to obtain a key of the account verification request. Determining (306) whether the mobile device identifier is a trusted identifier according to the acquired historical data of an account corresponding to the mobile device identifier may further include determining whether the key of the account verification request is identical with the preset key, if yes, the mobile device identifier is determined to be a trusted identifier.

The preset key is a key dynamically generated by the server system 108 according to a preset algorithm, and if the key of the account verification request obtained through parsing is identical with the preset key, it is determined that the device identifier is a trusted identifier.

In some embodiments, if it is determined, according to the acquired historical data of the account corresponding to the mobile device identifier, that the mobile device identifier is a trusted identifier, a positive response to the account verification request is returned to the mobile device. Otherwise, a negative response to the account verification request is returned to the mobile device. In some embodiments, after the positive response to the account verification request is returned to the mobile device, verification information, such as a password or a one-time pass code, sent by the mobile device, may also be received, so as to further perform verification of the account.

In method 300 for account verification provided in the present application, an account verification request sent by a mobile device can be received, where the account verification request includes a mobile device identifier. Historical data of an account corresponding to the mobile device identifier can be obtained. It can be determined according to the acquired historical data of the account corresponding to the mobile device identifier whether the mobile device identifier is a trusted identifier. In accordance with a determination that, an account verification response corresponding to the account verification request can be returned to the mobile device. Therefore, in some implementations of the present application, it is determined, according to historical data of an account corresponding to a mobile device identifier, whether the mobile device identifier is a trusted identifier, so as to perform verification for security and reliability of a mobile device on which the account is logged in to, and the security and reliability of account verification are improved.

In some embodiments, server system 108 first determines which of the first device and the second device has the scanning capability (e.g., which device has a camera that is capable of scanning), and then decides which device is to receive the encoded image, and which device is to submit the scanned result.

In some embodiments in FIG. 5D, server system 108 detects (526) a logged-on device (e.g., client device 104-2, FIG. 4D) that is currently logged into the first account (e.g, user account 431, FIG. 4D). Server system 108 determines (528) whether the account operation associated with the first account on the logged-on device is safe in accordance with the usage history data of the first account, and based on the one or more predetermined usage history criteria. The usage history data includes usage history data associated with the logged-on device. In accordance with a determination that the account operation associated with the first account on the logged-on device is safe, server system 108 identifies (530) the logged-on device as the second device for use in the verification process.

In some embodiments in FIG. 5B, the one or more accounts of the user used for determining the second device qualified as being safe include (514) the second account linked to the first account. In some embodiments, server system 108 initiating (508) the verification process based on the second device further comprises identifying (516) the second device based on the one or more predetermined usage history criteria and the usage history data associated with the second account; promoting (516) the user to perform a specified interaction involving the first device and the second device; and providing (516) a verification response to the first device in accordance with a verification of the interaction between the first device and the second device. In some embodiments, the usage history data includes (516) data regarding usage of the second account on the second device.

In some embodiments in FIG. 5C, the specified interaction includes (520) using the first device to scan an image containing encoded information displayed on the second device. In some embodiments, the specified interaction includes (522) using the second device to scan an image containing encoded information displayed on the first device. In some embodiments, the specified interaction includes (524) transmitting information via a short-range interaction means. In some embodiments, server system 108 first determines which of the first device and the second device has the scanning capability (e.g., which device has a camera that is capable of scanning), and then decides which device is to receive the encoded image, and which device is to submit the scanned result.

In some embodiments in FIG. 5D, server system 108 detects (532) a logged-on device that is currently logged into a second account associated with the user that is linked to the first account. Server system 108 determines (534) whether a predetermined operation associated with the second account on the logged-on device is safe, in accordance with the usage history data of the second account and based on the one or more predetermined usage history criteria. In some embodiments, the usage history data of the second account includes (534) usage history data associated with the logged-on device. In accordance with a determination that the predetermined operation associated with the second account on the logged-on device is safe, server system 109 identifies (536) the logged-on device as the second device for use in the verification process. In some embodiments, the first account and the second account are (538) accounts on two distinct platforms.

In some embodiments, the first account and the second account are accounts for different operating platforms, rather than a duplicate account of the user on the same platform. In some examples, the first account is a payment account and the second account is a social network account that is linked to the payment account, or vice versa. In some embodiments, the first account and the second account are determined to be associated with the same user by the server. For example, the first account and the second account have been frequently used by the same IP address, on the same device(s), and/or the registered information associated with the first account and the second account share the same information.

In some embodiments in FIG. 5E, server system 108 sends (542) an encoded image to the second device for display on the second device. In some embodiments, server system 108 sends (544) an instruction (e.g., notification box 434) to the first device to require an interaction between the first device and the second device. In some embodiments, server system 108 receives (546) a scanned result from the first device after the first device scans the encoded image displayed on the second device. In some embodiments, server system 108 verifies (548) whether the scanned result received from the first device matches the encoded image sent to the second device. In response to a verification that the scanned result received from the first device matches the encoded image sent to the second device, server system 108 provides (550) a positive verification response to the first device to allow the user to perform the account operation on the first device using the first account.

In some embodiments, the encoded image includes a 2-D QR code, or a barcode, or any other suitable scannable optical label. In some embodiments, the encoded image is displayed through the interface of the client application corresponding to the first account that is currently logged on at the second device. In some embodiments, if the second device qualifies as safe for a second account linked to the first account, then the encoded image is displayed through the interface of the client application corresponding to the second account that is currently logged on at the second device.

In some embodiments, the second device is the same device as the first device, and the first device qualifies as safe for a second account linked to the first account, in such a case, the encoded image may be copied from the interface of the second account, and pasted into the interface of the first account on the first device. In some embodiments, such copy and paste may not be required, since the server may determine that the first device is deemed safe for a second account that is linked to the first account, and thus provide a positive verification response without requiring the user to do anything.

In some embodiments, the verification includes verifying whether the encoded image sent to the second device matches the image of the scanned label received from the first device, and/or verifying whether the information included in the scanned label received from the first device matches the information included in the label sent to the second device. In some examples, the information included in the scanned label received from the first device may be responsive to or correlated with the information included in the label sent to the second device.

In some embodiments in FIG. 5F, server system 108 identifies (554) the second device that qualifies as safe for the account operation in accordance with usage history data associated with the one or more user accounts and the predetermined usage history criteria. In some embodiments, server system 108 determines (556) whether the second device is currently logged into a respective one of the one or more user accounts for which the second device qualifies as safe. In accordance with a determination that the second device is not currently logged into the respective one of the one or more user accounts for which the second device qualifies as safe, server system sends (558) an instruction (e.g., instruction box 470 of FIG. 4G), to the first device, to require the user to log into the respective one of the one or more user accounts on the second device within a predetermined time window (e.g., instruction 472 of FIG. 4G). In some embodiments, server system 108 monitors (560) whether the user has logged into the respective one of the one or more user accounts on second device within the predetermined time window.
